Do They Stall on Purpose?

I’m noticing that my items that sell for $50 or more ALWAYS sell after the payout window. My boxes have a mix of Free People, LoveShackFancy, Doc Martens, Alo, Lily Pulitzer, and Lululemon, a lot of it new with tags. The items that sell for higher amounts are going for non-reduced prices within days after the 30 or 45 day window, so I get nothing on a FP cocktail dress that sold for $90. It looks like sometimes they even raised the price later.

Is it possible their algo is suppressing the visibility/searchability of these popular brands until the window closes? I know the rules, but it’s all on faith and maddening to get $0 for my best stuff when it actually sold. Literally nothing has been returned to me or ended up unsold.
